We are testing out our server setup.
We have the following servers.
3 data servers
6 query services
2 index servers
We’ve noticed that the cbq-engine process on the query service servers are using 300% cpu usage without a reason. Looking at the admin ui, query service servers are processing only 3~6 n1ql queries per second. Most of our queries get timed out at this point.
How can I approach to debug/fix it?
We are on 4.1 enterprise with 3M+ documents and all of the queries are indexed.
